CHARLES H. THURSTON, OF BOSTON, MASSACHUSETTS.

HOOK.

SPECIFICATION forming part of Letters Patent No. 389,825, dated September 18, 1888.

Application filed May 14, 1888.

1?) all whom it may concern: Be it known that LOHARLEs H. THURSTON,

a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Vire Suspension-Hooks, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this speoification, in which-- Figure 1 represents a perspective view of a hook embodying my invention. enlarged sectional views taken through one of the semi-spherical heads on the outer ends of the hook.

My present invention relates to wire hooks for suspending garments, pictures, and various other articles, and has for its object to make a strong and secure wire hook with the least possible expense of time and material; and my invention consists in the improved hook hereinafter described, and in the application to wire hooks generally of an integral hemispherical or concavo convex enlargement, which is formed on the out-erend or ends of the hook by striking up the metal of said end with a suitable die, whereby an effective guard or protector is readily and cheaply formed, as I shall hereinafter describe and claim.

To enable others skilled in the art to which my invention appertains to make and use my invention, I will now describe its construction and indicate a preferred manner of carrying the same out.

In Fig. 1 the hook Ais formed of two pieces of wire, a and b, the former of which is formed at one end with a threaded tip or portion, 0, whereby the hook may be readily and securely fastened to the wall, door, or other place, while its opposite end is bent into the form of a hook at d, the outer end of which may be turned down, rounded, or otherwise formed with a head of a width sufliciently greater than the diameter of the main portion of the wire to obviate all danger of said end penetrating the material of the garment hung upon it.

The other wire or strand, b, is formed with a" hook and head corresponding with the hook on the wire a, and the two hooks stand in a line upon each side of the main portions of the Fig. 2 are.

Serial No. 273,870. (No model.)

wires, whereby a double hook is formed, and the said wire I), at its opposite end, is spirally coiled around the wire a at a point near the base of the screw portion 0 and in a plane at right angles with its length to form a bearing, which is adapted to rest firmly against the wall or other object to which the hook is at tached. The central portions of both wires a and b are twisted together, so as to materially strengthen the .hook, and the hook portions proper are formed on their lower ends and extend in opposite directions, as previously noted.

The hemispherical or concave-convex heads 6, which are formed upon the outer endsof the hooks, are of considerable importance, in that I am enabled to form said head integral with the hook by simply striking up the metal of the hook in a suitable die. When subjected to the action of the die, the metal is spread out or expanded in all directions, so that the width of the head is considerably greater than the diameter of the wire. At the same time the 'upper or convex surface of. the head is rounded in all directions, which not only makes aneat and ornamental finish, but also presents a bearing-surface sufficiently broad to obviate all danger of the end of the hook penetrating the material of the garment or article hung upon it. In addition to these very desirable features, I am permitted to effect a great saving of material when large quantities of the hooks are manufactured.

I am aware efforts have been made to accomplish the results previously referred to by turning the end of the hook downward and by turning and securing independent balls or knobs upon the ends of the hooks; but these modes are objectionable, because of the additional length of wireneeded to make the hooks when the heads are formed by turning the i is formed to prevent injury to the article hung upon it.

Having thus described niy'iuvention, what I claim as new, and desire to secure by Letters Patent, 1's- 1. A hook formed of the independent wires a and l), twisted together foraportion of their length and having at one end the oppositelyextending hook portions and at the opposite end a threaded tip or portion, and spirallywound bearing, substantially as described.

2. As an article of manufacture, a wire hook having the metal at the end thereof struck up to form a hollow hemispherical head having a
